thank you @Zax, I have seen it. I see that there are also different 1.1f firmwares. What is the difference between them? Is any compatible with the eleksmana board?

Thank you @Zax. I asked exactly because I want to use a better third party software, so I wanted to see if I already had the latest firmware.
Can I ask you for the simplest and safest way to upgrade my firmware?

Hello,

I just bought a EleksMana control board. It's a v 5.2 .
I was wondering which version of firmware is mounting? From the Wiki I only found a reference to EleksROM but on some laser engraving software I find only mentioned Grbl. Is EleksROM a variant build of the latter? If yes, at which Grbl version is it aligned?
